I'm looking to get a new Garmin wristwatch.
Broadly, I'm looking at the Garmin Instinct 2/solar and the fenix 6.
Neglecting the price differential, the main difference seems to be that the fenix has 1. Maps and 2. Color screen.
Specifically for multi day mountaineering expeditions, how useful is the maps feature? In general, teams have 1-2 handheld Garmin navigation devices, so it's not a must have. But is the maps feature actually usable/useful on watches? One difference I've read is that having maps allows better altimeter calibration with GPS data. But I guess I could also calibrate altitude manually using the handheld device. Are there any other use cases I'm forgetting?
